Ron Paul goes negative against Newt on air in Iowa

“We wanted to ensure this ad reached as many voters as possible, to debunk the myth that the Newt we are seeing on the 2012 campaign trail is the conservative he has been touted to be all along,” said Paul adviser Jesse Benton.

“The voters are looking for authentic conservatives who are able to show a decades-long career of consistently walking the walk of Constitutional principles, limited government and promoting sound economic policies. Ron Paul is the only Republican presidential candidate with that record.”

This will represent the first test of Gingrich's momentum and soaring poll numbers, and his organization's ability to counterattack.

Gingrich spokesman R.C. Hammond did not respond to an email requesting comment.
